Bug#531770: perl-modules: dpkg-source -x broken in file systems with ACLs due to File::Temp

[Russ Allbery]

Package: perl-modules
Version: 5.10.0-22
Severity: normal

windlord:~rra/home/tmp> dpkg-source -x *.dsc
dpkg-source: warning: extracting unsigned source package (libafs-perl_2.6.1-1.ds
c)
dpkg-source: extracting libafs-perl in libafs-perl-2.6.1
dpkg-source: info: unpacking libafs-perl_2.6.1.orig.tar.gz

windlord:~rra/home/tmp> echo foo > bar
windlord:~rra/home/tmp> cat bar
foo

It looks like Dpkg::Source::Archive just calls tempfile directly.

I suspect the code is using something like the -w file test, which is 
Broken As Designed unless you put "use filetest 'access'" at the top of
the module.  perldoc filetest has more details.
